Pittosporum vs Rain Lily Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Pittosporum
Pittosporum spp.
Pittosporum is a genus of evergreen shrubs and trees known for their glossy, leathery leaves and often fragrant flowers. They range in size from small shrubs to medium-sized trees, depending on the species. Pittosporums are primarily grown outdoors for their attractive foliage, which can be green, variegated, or even purple. Their dense growth habit makes them popular for hedging, screening, and ornamental landscaping. While some species can tolerate indoor conditions for a short period, they generally thrive outdoors with ample sunlight and air circulation. The appeal lies in their versatility and relatively low maintenance when planted in suitable climates.
Rain Lily
Zephyranthes spp.
Rain Lilies are small, bulbous perennials known for their delightful, trumpet-shaped flowers that often appear after rainfall, hence the name. They typically grow to a height of 15-30 cm. The foliage consists of slender, grass-like leaves. While they can be grown indoors, they thrive outdoors in well-draining soil and plenty of sunlight. People grow them for their charming blooms, ease of care (outdoors), and ability to naturalize in suitable climates. They are popular in rock gardens, borders, and containers.

❓ Frequently Asked Questions — Comparing These Plants
Pittosporum
What are the light requirements for Pittosporum?
Pittosporum thrives in bright, indirect light. Insufficient light can lead to leggy growth and reduced foliage density. An east-facing window is often ideal, providing gentle morning sun. A south-facing window can also work, but be sure to filter the light with a sheer curtain to prevent leaf scorch. North-facing windows may not provide enough light, especially during the darker months. Rotate the plant regularly to ensure even light exposure on all sides. If natural light is inadequate, supplement with artificial grow lights. Place the grow lights 12-18 inches above the plant. Observe the plant for signs of light stress, such as pale leaves or stunted growth, and adjust its location accordingly.
How do I care for Pittosporum?
Pittosporum prefers bright, indirect light. Avoid direct sunlight, which can scorch the leaves. Water thoroughly when the top inch of soil feels dry to the touch, ensuring good drainage to prevent root rot. Use a well-draining potting mix. Maintain moderate humidity levels, especially during dry indoor conditions. Fertilize every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune regularly to maintain shape and encourage bushier growth. Repot every 1-2 years, or when the plant becomes root-bound, into a slightly larger pot. Monitor for pests such as aphids and spider mites, and treat promptly if detected. Provide stable temperatures, avoiding sudden fluctuations or drafts. Ensure proper air circulation around the plant. Wipe the leaves occasionally to remove dust and maintain their shine.
How do I propagate Pittosporum?
Pittosporum can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist. Cover with a plastic bag or humidity dome to maintain humidity. Roots should develop in 4-6 weeks. For air layering, make a small cut on a healthy stem and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Keep the moss moist. Roots should develop in a few weeks. Once roots are visible, cut the stem below the rooted area and plant it in a pot. Ensure the pot is the correct size and the plant is secured.
Rain Lily
What are the light requirements for Rain Lily?
Rain Lilies thrive in bright, indirect light. Indoors, place them near an east- or west-facing window where they can receive several hours of sunlight daily. If you notice the leaves becoming pale or leggy, it indicates insufficient light. Conversely, scorching can occur if they are exposed to intense, direct sunlight, especially during the hottest part of the day. Rotate the pot regularly to ensure even light exposure on all sides of the plant. Supplement with grow lights if natural light is limited, especially during winter months.
How do I care for Rain Lily?
Rain Lilies are relatively easy to care for, requiring well-draining soil and bright, indirect light. Water thoroughly when the top inch of soil feels dry, and allow the soil to dry out slightly between waterings. Fertilize with a balanced liquid fertilizer during the growing season (spring and summer) to encourage blooming. Repot every 2-3 years or when the bulbs become overcrowded. Protect from frost in colder climates by bringing potted plants indoors or mulching garden beds. Deadhead spent flowers to promote further blooming. Provide adequate drainage to prevent root rot, and ensure good air circulation. Avoid overwatering, especially during dormancy.
How do I propagate Rain Lily?
Rain Lilies can be easily propagated by division. When repotting, gently separate the bulbs and plant them in individual pots. Offsets, or small bulbs that form around the base of the main bulb, can also be removed and planted. Stem cuttings are not applicable for Rain Lilies as they grow from bulbs. Keikis are not applicable for Rain Lilies. Ensure each division has healthy roots. Plant in well-draining soil and water thoroughly. Keep the soil consistently moist until new growth appears.
